Hi Ed, my mistake, the test started from cold, but the curve I've posted starts at a certain midnight. For completeness, the very initial warm-up is missing in the curve. Checking my archive, I see that the test started the previous day around 02:22 pm and the reading was 3 mHz higher, and I might have lost a few minutes since turning on the oscillators and the beginning of the record. The test was aimed at seeing how many days the Racal takes to stabilize around the 1E-10 level, and the answer was one week. And this is the overall sense of my curve. Hence a few minutes less or more were not important. But indeed this test is not a good indication of the very first warm-up minutes (intentionally not from stby).
